In a telnet session for imap, how can I calculate the value for octet to be passed in the search command. for example:
telnet 0 <port for imap>
. login <user> <paswd>
. select <folder>
. search charset utf-8 body {<octet value>}

4. Data Formats
IMAP4rev1 uses textual commands and responses. Data in IMAP4rev1 can be in one of several forms: atom, number, string, parenthesized list, or NIL.
4.3. String
A string is in one of two forms: either literal or quoted string. A literal is a sequence of zero or more octets (including CR and LF), prefix-quoted with an octet count in the form of an open brace ("{"), the number of octets, close brace ("}"), and CRLF.
In short, the number inside {} is the number of bytes(octets) or size of data which will be send from client to server.
For example: Suppose a mail needs to be stored in Sent folder via IMAP APPEND command.
A003 APPEND "Sent" (\Seen) "24-Oct-2016 14:16:00 +0530" {311}

Hello Jo2, do you think we can meet at 3:30 tomorrow?
Therefore, {311} is the size of mail.
